This Time Switch provides cooridinated control
for heater and filter pump operations. This two circuit switch is designed
to turn off a gas fired swimming pool heater approximately 20 minutes before
the filter pump shuts down. Eliminates the problem of pounding and knocking
due to overheated water, reduces scale and lime deposits and extends the
service life of the heater. The 24 hour dial allows up to 12 ON-OFF
operations each day. One set of "ON" and "OFF" trippers supplied with each
switch. Minimum ON-OFF time is one hour.
